Great review posted last week on Nextdoor by Michael McGeary:
We have a well with harder water than the city's. When we moved here in late 2013, we
installed a small device called a HydroFlow. You clamp it around the water pipe where it
enters the house, plug it in, and the electrical field causes the mineral ions to stick to each
other instead of the plumbing. We have a dishwasher and a Rinnai on-demand hot water
heater, and have never had a problem with them. We obtained it from New Water
Innovations, on Pacheco. They also have solutions for other problems. We eventually got a
reverse osmosis system for the kitchen sink from them, but because our well water has a
contaminant in it, not because of the water hardness. By the way, if you live downstream
from the airport, they also have a system for removing PFAS, which, unlike reverse osmosis,
removes the PFAS but then sends them down drain to the next person, retains the PFAS, so
they can be buried at the dump. I am sure you can google their reviews, and also
HydroFlow.
